Technically speaking the equation is incorrect. We now know that the speed of light isn't constant. Scientists in the laboratory have managed to slow light down considerably, and via quantum tunneling light can move faster then it would typically move. That isn't to say the equation doesn't work. Just that something thought to be a constant is not in fact a constant.


So the equation isn't actualy "incorrect". What you're saying is that it is unreliable due to the inconsistancy of the speed of light.
